Layered Filler Based Nanocomposite Polymer Electrolyte For Solar Cell Application

Priyanka Chawla, Mridula Tripathi


In the present work we fabricated natural dye sensitized solar cell using PVA based nanocomposite polymer electrolyte with MMT Clay (Montmorillonite) as layered filler in order to improve the conductivity of polymer electrolyte. In this work, we applied TiO2-WO3 to natural dye sensitizer solar cells as a photoelectrode to reduce the recombination rate by providing energy barrier and we also explore the use of natural dyes, betacyanin obtained from the beetroot which are characterized by a high content of red pigments with a high absorption coefficient in the visible part of the solar spectrum. The properties of the Polyvinyl alcohol based natural solid state dye sensitized solar cell have been studied by measuring their short-circuit photocurrent density (Jsc), open circuit voltage (Voc), fill factor (ff) and conversion efficiency.
